I never met Terachai, but he was responsive to the messages, so communication was easy and smooth. I had a great stay, my room with private bathroom was on the 4th floor, quiet, spacious, clean and comfortable. I had a great stay, I felt at home with nice neighbours. I met some other travellers and had a great chat with them. The place is located in a perfect area, close to everything: metro, restaurants, shopping malls, massage places, party area, etc...
I only suggest to have maps or information for people like me who was never in Bangkok before.
Thanks for the great hospitality! Hope to stay here once again in the near future. Totally recommended.
